When Ohio State plays Penn State on Saturday, the Buckeyes will again be without running back Jordan Hall.

The senior may even be out for the rest of the season with a knee injury. Ohio State head coach Urban Meyer said Wednesday that Hall, who hasn't played since Sept. 29, could redshirt.

Hall has had an injury-plagued year. Over the summer, he required tendon surgery in his foot after stepping on a piece of glass. Despite a partially torn knee ligament, Hall played against California and UAB. He had six carries for 26 yards and a touchdown against Michigan State, but left the game due to knee problems.

On the season, Hall has 40 carries for 218 yards and a touchdown. He also has three receptions for 31 yards.
